Welcome to the site, my main responce is in bold. We have had a few discussions about skipshift if you want to know more please use the search feature. Weight reduction is another issue. We only have guesses as to what can be done, but lightweight body pannels and such won't be available right away.

Thank you for the response.

I was not aware a shell is available. I will drive the car on the street even if only a 500 miles a year. Some tracks within 5 hours from the house I drive to. And I need it street legal if I decide to run One Lap of America.

The remark about seat replacement was meant as a figurative starting point for discussion of weight.
